Reducing heart disease risk in 12–15-year-olds with severe obesity

Mitigation of Cardiovascular Disease Risks in Children With Extreme Obesity (MODERN)

Observational University of Kentucky · NCT06967389

This will try semaglutide in 12–15-year-olds with class 2–3 obesity to see if it changes weight, heart-related risk markers, body composition, and fitness over about a year.

What this trial studies

This observational study gives semaglutide to about 50 adolescents (ages 12–15) with class 2 or 3 obesity seen at the University of Kentucky Pediatric High BMI Clinic and follows them for approximately 12 months. Participants will be titrated to a maintenance semaglutide dose and undergo baseline and ~12-month follow-up assessments including cardiac MRI or echocardiography, body composition testing, exercise/fitness testing, and blood and urine sampling. There is no randomization or placebo arm; all enrolled participants receive the drug and biologic samples will be stored de-identified indefinitely. The analysis will track how weight loss, BMI, body composition, heart structure/function, and fitness change together and whether sex or other factors influence outcomes.

Who should consider this trial

Good fit: Ideal candidates are 12–15-year-olds with class 2 or 3 obesity who are patients at the University of Kentucky Pediatric High BMI Clinic and meet clinical criteria to start semaglutide without exclusionary conditions.

Not a fit: Patients currently taking other anti-obesity or certain antihypertensive medications, with active organ disease, pregnancy, MRI incompatibility, or genetic syndromes associated with obesity are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, it could show semaglutide reduces BMI and improves heart structure, function, and fitness in severely obese adolescents, lowering future cardiovascular risk.

How similar studies have performed: Large adult trials have shown substantial weight loss with semaglutide, and emerging pediatric reports are promising though controlled pediatric outcome data remain limited.
